' Application filed April 11, 1918. Serial No. 227,875.

To all whom it may concern.

Be it known that I, WILLIAM EDMUND OREILLY, a subject of the King of Great Britain, residing in London, England, of H. M. diplomatic service, Foreign Oflice, Whitehall, S. W. 1., have invented certain new and useful Improvements in and Relating to Safety-Razors, of which the following is a specification.

This invention relates to safety razors of the type in which the blade is pivotally mounted between two members constituting the guard in a manner such that it may be swung away from the guard and handle, the means of attachment permitting the removal of the blade.

The present invention has for its object certain improvements in razors of this type whereby an attachment is provided, which is of such nature that, while the blade may be swung into and maintained in the desired position, the connection is of a resilient nature and will yield to permit the disconnection of the blade when so desired.

Figure 1 is a front elevation of a razor having a blade-holder andv blade according to the present invention.

Fig. 2 is a side view.

Fig. 3 is a section on line A A Fig. 1.

Fig. 4 is a front elevation showing an alternative form of the invention.

Fig. 5 is a back view of the razor shown in Fig. 5.

Fig. 6 is a section on line B B Fig. 6.

Fig. 7 is a sectional view taken on line C C Fig. 6.

Fig. 8 is a plan of a blade as employed in conjunction with the arrangement shown of a blade holder in Figs. 5 and 6.

Fig. 9 is a back view showing a further modification.

Fig. 10 is a section on line D D Fig. 9. Re erring to the accompanying drawings Figs. 1 to 5, a indicates the blade holder which in the example illustrated comprises a plate provided with turned over portions a forming resilient clips which bear upon the upper surface of the blade and so retain it in position on the blade holder. The p0rtion 0; is indented in any suitable manner so that at this point there is formed an inwardly directed projection b.

The blade 0 is provided as Shown more clearly in Fig. 8 with a perforation, c with which engages the projection 6 whereby while the blade may be swung into a position such as shown in dotted lines in Fig. 1, where it and the holder are readily accessible for cleaning purposes the said blade may be readily removed when so desired, by the use of suflicient force to cause the blade to ride over the projection.

Instead of the arrangement above described the projection may be formed with a gradual slope toward the near end and back of the blade holder, and have an abrupt face or edge looking toward the middle and front of the bladeholder, which shape together with the resiliency of the clip, permits of the blade being engaged or disengaged by movement from the end and back toward the middle and front of the bladeholder, but not by movement in the opposite direction.

In this arrangement as illustrated in Fig. l,- the ratchet-shaped projection is conveniently} formed by incising the bladeholder at e so as to form a tongue 6 The line of the tongue being inclined inward with respect to the line of the holder, so that the tongue points toward the middle and front of the bladeholder and it has its extremity turned or bent inward so as to engage the perforation in the blade. The blade can be inserted by a movement in the direction of arrow to and withdrawn by movement in the same direction when, for instance, in the position shown by dotted lines 0 In the position 0*, however, it cannot be withdrawn because its end abuts against the side of the clip at the point y which prevents it from moving in the direction necessary, as. already explained, to effect its withdrawal.

Instead of the projection being formed as an integral portion of the bladeholder, it may be constituted by a piece of suitable metal f riveted or otherwise secured to the bladeholder, Figs. 9 and 10.

Claims:

1. A safety razor comprising a handle, a

blade, a bladeholder, and a resilient detachable pivotal connection between said holder and said blade. 2. A safety razor comprising a handle, a blade, a clip-like blade holder, and a resilient pivotal connection between said holder and said blade, said connection being adaptcd to yield to ermit the disconnection of the blade only when said blade is moved in a predetermined direction.

3. A safety razor comprising a handle, a blade, at clip-like bladeholder, and a resilient pivotal connection between said holder and said blade, said connection being adapted to yield to permit the disconnection of the blade only when said blade is moved in a predetermined direction, comprising a proj ection upon one member of the bladeholder, and a housing for said projection upon the blade.

4. A safety razor comprising a handle, a blade, a clip-like bladeholder, and a resilient pivotal connection between said holder and said blade, said connection being adapted to yield to permit the disconnection of the blade only when said blade is moved in a predetermined dlrection, comprlsing a projcction upon one member of the bladeholder, a projection upon the other member of the bladeholder and a housing for said projections upon the blade.

5. A safety razor comprising a handle, a blade, a clip-like bladeholder and a resilient pivotal connection between said holder and said blade, said connection being adapted to yield to permit the disconnection of the blade only when said blade is moved in a predetermined direction, comprising a resilient tongue upon one member of the bladeholder, an inwardly directed portion on said tongue, a perforation in the blade engaging said tongue.

6. A safety razor comprising a handle, a blade, a clip-like bladeholder and a resilient pivotal connection between said holder and said blade, said connection being adapted to yield to permit the disconnection of the a blade only when said blade is moved in a predetermined manner, comprising a re silient tongue upon one member of the bladeholder, an inwardly directed portion on said tongue, a perforation in the blade engaging said tongue, said inwardly turned portion of said tongue having its outer portion so shaped and being so disposed that the tongue will only yield whenthe blade is in a predetermined position.

7. A safety razor comprising a handle, a blade, a clip-like bladeholder, and a resilient pivotal connection between said holder and said blade, said connection being adapted to yield to permit the disconnection of the blade only when said blade is moved in a predetermined direction, incisions in one member of the holder forming a tongue, an inturned portion upon said tongue, a rounded surface at the outer end of said inturned portion, said tongue being so positioned that it will yield only when the blade is in a predetermined position, and a perforation in the blade engaging the inturned portion of the tongue.

In testimony whereof I afiix my signature in the presence of two witnesses.

WILLIAM EDMUND OREILLY.
